When handling phosphoric acid, it is essential to use appropriate personal protective equipment (PPE) to ensure safety. The required PPE includes:

1. Eye and Face Protection: Use approved eye and face protection to prevent splashes from reaching the eyes and face. This can include safety goggles and face shields [1].

2. Protective Clothing: Wear protective clothing that is resistant to acids to prevent skin contact. This may include acid-resistant gloves, aprons, and full-body suits depending on the concentration and amount of acid being handled [1].

3. Respiratory Protection: If there is a risk of inhaling vapors or mists, use appropriate respiratory protection. This could include respirators that are suitable for chemical exposure [2].

4. Foot Protection: Wear chemical-resistant boots to protect feet from spills and splashes.

Ensure that all PPE is maintained in a sanitary and reliable condition, and that employees are trained in its proper use, limitations, and maintenance [2].

Additionally, it is important to have an eyewash station and safety shower accessible in the area where phosphoric acid is handled, to provide immediate decontamination in case of exposure [3].
